Hints:

"no-aging" diets,

unsubstantiated

fertilized

fumigated 

Almost daily the public is besieged by claims for "no-aging" diets, new vitamins and other wonder foods. There are numerous unsubstantiated reports that natural vitamins are superior to synthetic ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than fumigated grains and the like. One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern if consumers particularly those with limited incomes, distrust the regular food supply and buy only expensive organic foods instead.
公众几乎每天都被“抗衰老”食品、新型维生素以及其他具有神奇功效的食品广告所包围。天然维生素优于人造维生素、受精蛋比未受精蛋的营养价值更高、未经熏蒸消毒处理的谷物比经过处理的好等等，诸如此类的毫无根据的报道屡见不鲜。 大多数有机食品有一个共同点，即它们的价格普遍高于以常规方式种植的食物。但在许多情况下，如果消费者认为有机食品能保证健康且营养价值高于以常规方式生产的食品，他们其实是被误导了。如果消费者们，尤其是那些收入有限的消费者们，怀疑传统食品而只购买更昂贵的有机食品，那就值得担忧了。
